Enable high contrast without enabling reduced transparency on macOS Big Sur

As it says in the title

Is there a way?

I suffer from astigmatism, and in all sorts of devices enabling some sort of high contrast mode enables me to find my way faster around the UI. On my iPad [iOS 14.4] I can very easily enable high contrast mode without enabling reduced transparency - however my MacBook running macOS Big Sur 11.2.1 forces reduced transparency on me whenever I enable high contrast mode and doesn't give me an option to disable reduced transparency with keeping high contrast enabled.

What gives? Is there a way? Is this by design, of for some reason just impossible to do? If not an option officially yet, how do I submit feedback?
